WMR Samsung Odyssey cannot connect to steam VR with error code 301 after this update/ how can i use old version?

fxd error 301
go to Steam\steamapps\common\MixedRealityVRDriver\resources\settings
edit default.vrsettings

// Disable DX12 support
"forceDisableDX12": false

change to

// Disable DX12 support
"forceDisableDX12": true

started having a deadzone problems now. tried playing Moss, really painfull to play the game.

Still having the issue with what i think is actually the Default.vrsettings file not being read. Any changes to the file seem to have no effect. Originally noticed with the Reprojection setting but same issue with just showing the repro indicator too. LKG_Release version still the only version that works, either there is an error in a path somewhere that i can't find and only came in after LKG version, or something is causing file not to be read.

the same problem with HP Windows mixed reality and 301 error. it don´t work now..

me: time to enjoy some VRchat... Steam: opens.. Me: nic- Steam: closes. Steam: repeats process for 2 full minutes... Me: p l e a s e s t o p

it was all a clear image, as if rendering was not 2.0, but 0.3 everywhere. Everywhere bumps along the edges and stairs and a blurry image. In Steam VR rendering does nothing but load. image quality everywhere has become terrible.

Fer109 you need to go in steam vr "the app" not windows mixed reality for steam vr(when you plug in your headset it puts you in windows mixed reality"not for steam vr " then click on the little circle with "VR"written in it then it'll launch steamvr home and then you can launch the game).

PS: I have the lenovo explorer too
